生成隨機(jī)密碼這件事情用python來干確實(shí)相當(dāng)?shù)姆奖悖瑑?yōu)美的string方法加上choice簡直是絕配
make_password.py
###簡單幾行代碼執(zhí)行即可生成記不住的字符串###$ python make_passwd.py DLrw9EiT Qs4Wm84q RQwl4L2L u9g0LgwW jHPtYdyU ...
$ python make_passwd.py DLrw9EiT Qs4Wm84q RQwl4L2L u9g0LgwW jHPtYdyU ...
代碼如下――注釋比代碼長

生成一些人似乎能好記一些的密碼(Qs4Wm84q這種密碼似乎除了復(fù)制粘貼沒有別的選擇，話說前年我使用shell生成的類似的密碼給ldap做默認(rèn)密碼，我當(dāng)時公司就真有員工把這樣的密碼背下來了，現(xiàn)在想想真心是厲害~~~)。
##這樣看起來是比上面的好記一點(diǎn)了吧，但需要提供一個字典文件##$ python make_dictpass.py 1 8 1 ipythosd$ python make_dictpass.py nahontchen chenyibfeo ipythoniue coreostche ...$ python make_dictpass.py 1 8 1 ipythosd$ python make_dictpass.py nahontchen chenyibfeo ipythoniue coreostche ...
